The goal of Web based employees quality and events management system is to solve the information transmission problem between employers and employees. The problem lies where employer has to be sure that certain information like schedule, time and place or another relevant information is properly communicated to employees. While ordinary schedule's problem has been solved for years the problem is still present for those employees who work irregular work hours, different locations and have to know specific information about their work and it is not easy to calculate working hours and salaries for those employees. This bachelor thesis has been aimed to solve this problem by providing employers clear and easy way to manage schedules, communicate necessary information, monitor employees performance and calculate salaries.

This bachelor thesis is designed for a contactless sensor system. This system is designed to monitor whether fluid spills have been detected. The system consists of a sensor that captures distance and its change, a microcontroller - responsible for sensor control and sensor data transfer to the server using TCP protocol. It also consists of a server that receives the sensor data and places it in a database for viewing and further analyzation or the data can be transferred to other interfaces. Analyzing analogous systems and sensors, reviewing system designs and equipment used. Designed block diagram, schematics. Sensor and server programming, testing. Possible ways of improving the system were reviewed.

Voltage downgrade converter testing device. Bachelors thesis for electronics engineering degree. Vilnius Gediminas technical university. Vilnius, 2019, 51 p., 34 pictures, 2 tables, 13 lit., 5 ex.
The main objective of this bachelor thesis is to create a device that could perform voltage downgrade converter tests autonomously. This would help raise work effectiveness for electronics engineers in UAB “Teltonika”. Our device would enable them to test power circuitry effectiveness and load response quickly.
To create desired test conditions for the step-down converter our system has two electrically controlled loads. They are both connected parallel to each other. One of the circuits is for generating constant loads and the other one is for fast transient loads. The size of both loads can be controlled via the user interface. Constant current load represents the average consumption of some device under test (DUT) and the transient load simulates an activation of various modules within the device. If the power circuitry is reliable the output voltage of the step-down converter should not fluctuate too much. Our system is capable of measuring this phenomenon and reporting the results to the user in real time.
The device is now being used by engineers in UAB “Teltonika” and makes power circuitry testing much faster and easier. That being said, we can conclude that the main goal of our thesis has been achieved successfully.

Investigation of gesture language features. Master's Thesis for Informatics Engineering. Vilnius Gediminas Technical University. Vilnius, 2019, 50 p., 23 pictures, 1 table, 31 references, 2 annex.
The aim of the master's thesis is to create and investigate the algorithm for calculating gesture language features. Analogical systems are analysed in this work. Open source libraries create a convolution neural network training algorithm. Training images are obtained from freely available databases and photos.
The database is prepared with a large number of photos. The aim is to improve the results of the training algorithm using a large amount of data to produce a more accurate result.
A personal computer is used during work. The computer window displays the results obtained and algorithms created.
